Figure 4. Connecting Water Supply

PlumbingNOTE: Miracle Steamer models are

designed to use cold tap water. Distilled water may be used to reduce calcium/mineral deposit buildup and reduce maintenance costs.

These units require a direct cold water hookup. A Water Inlet Hose and Strainer Assembly (Figure 4) is supplied.

NOTE: Incoming water is controlled by a normally closed (NC) sole-noid valve located inside the Steamer’s electrical housing.

1. Turn off the water valve (not sup-plied) that supplies water to the unit (Figure 4).

2. Connect the 1/4” (6.5 mm) I.D. Flexible Tubing to the outlet side of the Water Pressure Regulator and secure using the Worm Clamp (Figure 4).

NOTE: A Water Pressure Regulator must first be installed (Figure 4). Failure to do so will result in poor steaming and possible flooding. For a single steamer, use Water Pressure Regulator P/N 7000314. For two adjacent steamers, use Water Pressure Regulator P/N 7000235. For Mfg. No. 9100933 use only P/N 0012001.

CAUTIONWater pressure must not exceed 30 psi

(2.1 kg/cm2 or 207 kPa). Higher pressure may cause poor performance or flood-ing. To reduce water pressure, install a

Water Pressure Regulator, and set to 20–25 psi (1.4–1.7 kg/cm2 or 138–172 kPa).

3. Turn the water valve on.

4. Hold the Quick Disconnect Insert over a bucket, then press and hold the white plastic tip until there’s a good, steady water flow. This will purge all air out of the line.

5. Release the plastic tip and check the pressure on the Water Pressure Regulator. It should read 20 psi.

a. If it reads less, increase the water pressure by pulling the black knob up and turning it clockwise.

b. If it reads more, decrease the water pressure by pulling the black knob up and turning it counter clockwise.

NOTE: When adjusting the knob, relieve the existing pressure by press-ing the plastic tip on the Quick Disconnect Insert for 3 seconds. The Water Pressure Regulator will then show the new pressure.

6. Once the regulator reads 20 psi, push the black knob down to lock it in place.

7. Push the Quick Disconnect Insert into the fitting at the rear of the unit until it clicks (Figure 4).

MonthlyThe Miracle Steamer utilizes an open steam Generator. Water sprayed onto the Generator surface flashes into steam im-mediately, but the minerals in the water do not steam, they stay on the Generator surface. A small amount of calcium/mineral deposits are needed for proper operation, but a buildup of excessive calcium/mineral deposits causes poor steaming efficiency and excessive moisture (wet steam), which will eventually severely hinder the steaming action.

Cleaning Steam Generator

1. Turn the power off, unplug the power cord, and allow the unit to cool down.

2. Perform the Daily cleaning, but do NOT reassemble the unit.

3. Remove the Wing Nut, Generator Cover, and Diffuser (Figure 11). Wash these items in hot, soapy water, rinse and WIPE DRY.

4. With the unit cool, use a wire brush and/or scraper to loosen and remove the excessive calcium/mineral deposits from the Generator surface.

5. Take a wire brush and clean out any buildup from the 28 Steam Ports (26 vertical and 2 horizontal) of the Generator (Figure 11). Remove the loose buildup, wipe the Generator with a clean, damp cloth, and reas-semble the unit.

NOTE: If deposits are still excessive and/or difficult to remove, refer to Steps 6 and 11.

6. Pour delimer solution (not supplied) onto the Generator surface. Follow the delimer manufacturer’s instruc-tions for proper mixture and use.

7. Using a sponge or a dry towel, re-move the delimer solution from the Generator surface, then rinse with clean water.

NOTE: To ensure proper steaming characteristics, some calcium/mineral deposits must be pres-ent on the Generator surface. If, during cleaning, the surface does become free of calcium/mineral deposits, add plain tap water to the surface and allow it to boil off. If necessary, repeat this pro-cess to formulate a thin coating of calcium/mineral deposits.

NOTE: In soft water areas, it may be nec-essary to add a small amount of lime to the Generator to “season” it. This will ensure proper steam-ing characteristics by producing a thin coating of calcium/min-eral deposits on the Generator surface.

Seasoning mixture consists of 3/4 ounces (25ml/ 25cc) baking soda, 3/4 ounces (25ml/25cc) lime mixed with 1 quart (950ml/950cc) of water. Stir mixture and pour 1/4” deep onto the hot Generator sur-face. After mixture is converted to steam, the remaining loose power can be removed.

8. Plug the power cord into the appro-priate outlet.

9. Turn the power on and allow the unit to warm up for approximately 30 minutes.

10. Push and release the Operate button or the Start/Stop button several times to operate the steamer. This purges any remaining delimer resi-due from the Generator surface.

11. Turn the power off, reinstall all parts and accessories, and return the unit to service.

CAUTIONIf a chemical cleaner/delimer is used,

be sure it is safe to use on cast alu-minum. Observe all precautions and

warnings on the product label.

Checking and Cleaning the Water Strainer

The Water Strainer protects your equipment from any foreign debris in the water line that could get into the food or damage the unit’s solenoid and cause the unit to leak or flood. It also protects the equipment’s proper and consistent operation from interference.

To ensure proper and consistent steaming results, check the Water Pressure Regulator and Strainer Cup regularly. If the pres-sure has dropped, check the Strainer Cup and clean out the accumulated debris as follows.

1. Shut off the water supply valve to the unit, unscrew the clear, plastic Strainer Cup and carefully remove the Mesh Screen.

2. At the sink, gently flush all of the ac-cumulated debris from the Strainer Cup and Mesh Screen. Be especially careful not to damage the Mesh Screen.

3. Carefully place the Mesh Screen into its seat at the bottom of the Strainer Cup and confirm that the orange O-ring is properly seated in its place before screwing the Strainer Cup and top back together.

4. Purge the air out of the strainer and tubing by disconnecting the Male Quick Disconnect Insert from the equipment and, over a bucket, push the white plastic tip in until there is good water flow.

5. Replace damaged or worn parts as needed.

6. Verify that the Water Pressure Regulator is set to 20–25 psi (1.4–1.7 kg/cm2 or 138–172 kPa).
